Food Into Poop; Drink Into Pee

I can turn food into poop
And drinks into pee
And I can do it all unconsciously
I've got a truly amazing and magical body

You're welcome to observe it, though it might make you sick
I suggest you wear a gas mask as I do this trick
Turning my meal into excrement

Listen up closely to my suggestion
You should be in awe of your body's digestion
Be enchanted, don't take it for granted

'Cause you can turn your food into poop
And your drinks into pee
And you can do it all unconsciously
You've got a truly amazing and magical body
